Hammond PBR50EXT Stack Light Tube Adaptor Extension

The PBR50EXT is a stack light tube adaptor, listed by the manufacturer with the short description "Stacklight Extension". It is an accessory for the PBR Series modular stack light system and is intended for panel builders, machine builders and maintenance teams who assemble or modify PBR signal towers.

The PBR series is designed around separate components so that each installation can be ordered to suit its application. A tower is made up of a base, a mounting stand or tube, and up to five light stages, and the series lists stand mounting, tube mounting and direct mounting as installation methods. The PBR50EXT is the tube adaptor part within that system.

The manufacturer data for the PBR50EXT itself is limited to its description and identifiers: it is REACH compliant and RoHS compliant, has a shipping weight of 1 lbs (0.45 kg), and carries UPC 623980004280 and UNSPSC 39112001. No dimensions are published for this part, so confirm fit against your tower configuration before ordering.

For context, the PBR system it belongs to is rated IP 54, is specified for an operating temperature of -25 °C to +45 °C, and can be installed vertically or horizontally. The series uses polycarbonate light modules, an ABS plinth and a stainless steel tube, and it offers threaded tubular stands in several lengths (PBR50T100, PBR50T250 and PBR50T400) as well as tubular stands with plinth (PBR50S100 and PBR50S250).
